Mercy is a mystery through and through, and kept me guessing the entire time. I read the blurb first, but it took me awhile, even longer than Mercy as Carmen did to figure out what was going on. I enjoyed reading it, and it was a great story but I was confused a lot. There are great characters, either that I could relate with and love like Carmen and Ryan, and the characters that were wonderfully written to make me hate them so bad. If you like mysteries and want a new twist on angels, this is the story for you.
